My Lesco 36" WB has been slowly losing its transmission. I was happy to finish up the year without having to do surgery on her. I now want to replace the transmission which I have never done before but I wanted to make sure there were no surprises after I started. I know it is a Tecumseh 5 speed tranny. Any suggestions would be appreciated. Also anyone have a guess on how long it will take to replace? Thanks. Also I know it is the tranny and not just the belt under the frame as I have kept it plenty tight.
